To all whom. it may concern:

Be it known that 1, MAX Hnnsuovrrz, a citizen of the United States,residing at Chicago, in the county of Cook and 'State 5 of Illinois,have invented anew and useful Improvement .in Electric-Lamp-SupportingStructures, of which the following is a specification.

My invention relates more particularly,

19 though not exclusively, to electric-socketsupporting structuresof thetype which are supported from a. base, as is common with table or'floorlamps. One of my objects is to provide for the supporting of theelectricbulb-receiving sockets in a manner to permit the sockets to beadjusted into different positions relative to the part which supportsthem, preferably to cause the bulbs provide a new and improved form'ofcombined housing for the electric wires and support for the socket orsockets, and preferably also for switch mechanism controlling thesupplying of current to the bulbs, which shall be strong and durable andmay be used ina variety of locations and used with either of itswire-receiving tubular portions uppermost; to provide a plural socketconstruction of the type above 'referred to which will permit of thewiring connecting the socketinteriors, and the switch where such isprovided for enclosure in the. casing, being wired before assembly withthe housing structure; and other objects as will be manifest from thefollowing description.

Refeiu'ng to the accompanying drawings:

Referring moreparticularly to thestructure illustrated in Figs. 1to 12 inclusive,

wherein my invention is embo diedin .an- I electricsocket-supportingstructure of the type involving a base (not'shown) at which thestructure is adapted tobe supported, as forjexampleon a'table or afloor, with a standard rising therefrom and supporting adjacent itsupper end, :the upright, or standard, portion, which is shown as formedof a tube,is represented at 19, this tube not only serving as a'support;but also serving,

to enclose the electricecurrent conducting wires which lead to thebulb-receiving,

sockets hereinafter referred to.- The upper end of the tubularupright'19 is secured to a housing member represented generally at 20,as by screwing the member 19 into the hollow depending'boss portion 21of the housing 20. This boss member 21 is provided as a partof ,aring-shaped member 22 which isl formed, preferably integrally, wit-h Ian upwardly-extending, boss 23 preferably in vertical alignment with theboss 21. The housing portioii'20 also comprises cap plates 24 and 25 ofgeneral dish shape as shown,

preferably. of semi-spherical form, which are adapted to be assembledwith the ringshaped member 22 at the opposite ends of theopeningtherethrough, in a manner here inafterdescribed, to complete thehousing and cause "the latter to beof substantially spherical-form asshown, thetcap-plates 24 and 25 being each provided withdiametrically-opposed outwardly-extending" lugs 26,

at their open sides. The ring member 22 is preferably provided atopposite faces with annular flanges 27 with qwhiclr the cap plates 24and25 telescope when thelatter are applied tothe member- 22 .v The ringmember 22 is also provided with diainetrica'lly-opposed bosses 28 and 29which prefershoulders 31 and 32at the ends of these grooves. The bosses28 and 29 are hollow, as represented more particularly in Fig. 8, thepassages therethrough and represented at 33 Opening into the interiorofthe ring member 22,.and the outer surfaces of these bosses Y at'oneffaceo'f the ring member 22 from the adjacent flange 27 to the grooves 30,containing recesses 34 which extend lengthwise of these bossesthroughout the length of the "latter and open into the interior of themember 22. The bosses'28 and 29 atpoints diametrically opposed to therecesses 33, are

cutaway from their outer extremities to the inside of the ring member22, asrepresented at 'lVhcn the cap sections 24 and 25 are applied and11, the recesses 34 and 35 receive the lugs 26 of the caps which, becomepositioned on the" ring member 22as disclosed in the drawings, moreparticularly. Figs. 4 and 11.

- The bulb-receiviiig sockets of the structure are represented at 136,these sockets being formed with hollow shells 37 provided withlaterallyrextending hollow portions 38 open ing into the interiors oftheshells 37 and to position at opposite sides of. the ring vmember 22as shown in Figs. 4

containing bo res 39 of circular shape in cross section' adapting ,thesesockets to be telescoped at their portions 38, with the a V bosses 28and '29 as shown in Fig. 11, these I Y i socket portions when assembledwith 1 the ring member 22 overlapping the lugs 26 oi the caps 24 and. 25and holding the latter in I place on the ring member 22. The'p'ortions38 are equipped with set-screws 41 which extend at their innerends, asrepresented of the one in Fig. 12, into the c rcumferential grooves 30in the bosses 28 and 29, thereby holding these socket members 36 againstaccidental disengagement from the housing.

member of which the. ring 22 is e: part,

while permitting of the independentrota tion ofthe socketnnembers onthis housing except as limitedby the stops 3l and 32 which are providedprimarily "to prevent undue twisting of the electric-current-com ductingwires extending, into the sockets,

The socket members 37; contain socket interiors (not shown), inaccordancewith common practice, these socket interiors be ing of anysuitable construct onand afford-K ing contacts for the lampand, jasshown, be- 7 7 ing formed with ai'i outer screw-threaded vcontactv42 anda centercontact 43. The" wires (not shown) leadingintothe housing 20,for conducting current to the sockets, are connected with a terminalblock represented at44 which may be of any suitable constructionadapting of the connection of the lead wires thereto as represented at45 and 46, the various wires represented at 47 48,-

49 and 50 and extending through the bosses 38 and electrically connectedwith thecontacts of th'e socket interiors referred 'to,'be-

ing connected at the block 44 with the ter-" ll'llIlZllS 45 and 46 in amanner to' supply cur-- rent to both of these socket interiors, as willbe readily understood by those skilled in the art, the terminal block 44being formed with an outer shell 51 containing wax, represented at 52,for holding the wires 47, 48, 49 and 50 rigidly in place, and also beingprovided with a cover section at one r end, as represented at 53, theterminal block a .44 being shown as of the type involving,

switch mechanism operated through .the medium of the the flow of currentto the socket interiors 1 referred to.

In the particular arrangement shown the sockets may be wired to theterminal switch mechanism 44 before the assembly thereof.

with the housing structure 20, and .these' parts then assembled byintroducing the terminal switch mechanism 44 into the ring shaped member22, the wires leading tothe- 'socket'interiors being positioned in thebores 33 through the open sides 34 thereof, wherei are applied" upon thecap plates .24and 25 to the ring member 22 to the osition stated aboveand theportions 38 o the shells 37 pull-chain 54 for controllingtelescoped with the bosses 28 and 29 to a position in which the portions38 overlap the lugs 26, whereupon the set-screws T1 are turned to extendat their inner ends into the grooves in the bosses 28 and 29, the leadwires extending upwardly through the pipe 19 and boss 21 of the housing20 being attached to the terminals and 46 before the cap plates 24- and25 are positioned as stated. The deviceas shown also provides "or thesecuring to the upright portion the structure, of a lamp shade, thebeing se curable at different elevations. fected in the particularstructure shown by the provision of a threaded rod which screws into theupper boss 23 and carries two discs 55 and 57 threaded thereon, theupper end of the rod 55 being shown as provided with anornanientalsection 58. By

virtue of the adaptability or" the rod 55 to adjustment up and down onthe housing 20 and the adaptability oi the discs 56 and 57 toindependent adjustment on the rod 55, the structure is adapted tosupport shades at different elevations relative to, the housing 20-andin a manner to present an ornamental appearance.

By providing the hollow bos es 21 and 28 the structure'may be assembledwith the supporting structure, shown in the drawings as an upright,either in the position shown, or in inverted position, or wires may heled in through both of the bosses 21 and 23 as desired.

While the structure is shown as involving its support from a stand, itwill he readily understoot that it may be embodied in a chandelier, inwhich case the upper boss would connect with the part depending from theceiling and supporting the fixture and the shade-holding means, ii used,would be connected with he lower boss 21.

The structure shown in Figs. 13 to 18, inclusive, involves amodification of the structure shown in the preceding figures wherebymore than two of these socket members 36 may ,e rotatably supported onthe central housing member. In the construc} tion now beingdescribed'this housing member, represented generally at 59,, is formedof a lower hollow section 60 and an upper hollow section 61, the lowersection 60 containing a boss 62 opening into the interior of the housingand correspondinnwith the boss 21 or the preceding figures and the uppersection 61 being provided with a boss 62 openi, Y into the interior ofthe housing and corresponding with the boss 23. The lower housingsection 60 is provided with outwardly-extending bosses 6% which extendsubstantially horizontally, and are shown as radiating from the centerof the housing, in the particular construction shown four of thesebosses being provided and forming journaling supports for fourlamp-receiving This is er? scopes with the wall of-the section'GO at theopen end of the latter, is provided with radially-extending lugs 71'whlch, when the section 61 is assembled with'the section 60,

extends into the slots in the section 60; The portions 66 of the socketmember 65 upon being applied to telescoping position as shown in Figs.13, 14 and 18, overlap the lugs 71, the'reby holding the sections 60 and61 together to form the :housing structure, the side wall of the section61 ,at the open end of this section, being recessed as represented at 72to straddle the bosses 64. The SOClIGt portions 65 are provided withsetscrews, represented at 7 3, extending at'their inner ends into the=g1oove67 and functioning as explained of the set-screwsl of thepreceding figures.

In this construction the same shade-securing means are provided asexplained of the construction in the preceding figures, the somenumerals being applied to similar parts which are carried by the upperhousing section 61 instead of, the substantially verti-' cally disposedring member 22 of the preceding figures.

It will be noted that the construction'of Figures 13 to 18 inclusivepermits, when the housing section 61 is removed, the assembly with thesection 60 of the terminal switch block corresponding'with the block 141of the preceding figures, and the wiresleading therefrom into the socketinteriors l-:: :ated in the socket. portions 65, into the section 60, inassembled condition, inasmuchv the bosses 6% contain the slots 70, thepull-chain for actuating the switch referred to being represented at'75and operating in a chain-guide 1 6 in accordance with com mon practice.i Y

It will benoted that in both of the constructions described, the socketportions are rotatably mounted on the central housingmember and may berotatably adjusted thereon to cause these sockets and the bulbspositioned therein, to extend into different angular positions, asdesired. I

Furtherinore it will be noted that a structure embodyingfmy inventionmay be con structedvery economically, is simple of con struction andpresents iighly ornamental appearance.

.The set-screws 41 and 7 3 and 74 as pro videdlm'ay'also serve thepurpose, by screwing themto engage at their, inner ends with the bosses28, '29 and 70, of holding the sockets in any position to'which they are.adjusted on these bosses.

' While "I have illustratedtwo embodiments of my invention, I do notwishto be understood as intending tolimit it"thereby, as the same may bevariously modified and altered, and the invention embodied in otherforms, 7 without departing r from the spirit of my invention.
